摘要
本文介绍重质石油产品试样于容积350rnl的氧弹中,在3MPa高压氧的条件下燃烧,样品中的硫氧化为三氧化硫,用碱液吸收后进行离子色谱测定。对润滑油、柴油、凡士林、渣油测定结果相对偏差小于5％,平均回收率大于92％。
Samples of heavy oil products are placed in 350mL oxygen bombs and burnt under the condition of 3MPa high pressure oxygen. The sulphure in samples is oxidized to sulphur trioxide which is absorbed in alkaline solution and then determined by ion chromatography. Lube oil, diesel oil, petrolatum and residual oil are tested. The relative deviations are less than 5% and the average recoveries more than 92%.
